To all whom it may concern: of construction and combination as herein- Be it known that we, KELLEY M. TURNER after set forth and claimed.

Referring to the drawings, 1 designates a Our invention relates to telephonic apbattery case of the usual fiat form with paratus adapted to be used by deaf persons rounded side edges 2 adapted to fit snugly in and comprising a portable transmitter, rean ordinary vest or other pocket.

The entire clamp is metal with a base 13 which may be soldered or otherwise fixed to the cover 3, and laterally deflected ears 1 1 at the extremities of the arms which have inwardly directed pins 15. The rear face of the transmitter 6 is stamped or embossed with protuberances 16 behind which the pins 15 are adapted to engage. In this relation the transmitter is held vertically above the recess 8 of the cover, into which it projects slightly in the manner already described.

The circuit connections are established from the battery and transmitter to the receiver 17 through a flexible cord 18 of the ordinary sort. In order to have the circuit connections as neat in appearance as possible, we provide the battery case cover 3 with a pair of notches 19 adjacent to its lower edge through which the separate branches 20 of the battery connection pass. The transmitter connection 21 is made from a point or junction 22 sufiiciently distant from the battery to enable the latter to be located in one pocket, while the transmitter is hung on an outer garment in case of its separate use. 23 designates the usual clasp by which the transmitter is attached under these circumstances. In case the transmitter is associated upon the battery case, however, the separate battery leads 20 and the joint 22 are all massed together and pushed into the cover 3, in which case the receiver and transmitter connections 18 and 21, respectively, are passed outward through the slots 19, in place of the separate battery leads, as first described. The apparatus is there fore substantially as neat in either manner of its use, as in the present systems which are individually designed for each separate plan. The transmitter is very firmly associated upon the battery case in use on access 8 already described, and on account of the comparative stiflness of the arms 12 in a forward or rearward direction. The resiliency of the arms maintains their pins 15 in close engagement with the protuberances 16 of the transmitter, which engages ment keeps the transmitter pressed downward closely into its recess 8, resisting any sidewise or lateral movement. The transmitter is quickly disassociated for separate use by springing apart the arms 12, after which it is freely remo able.

\Vhat we claim 1. A telephone apparatus comprising a transmitter, a receiver, and a batteiy case, said battery case having a removable cover, flexible cord connections extending from said transmitter and from said receiver and joined to a pair of battery leads, means for fixing said transmitter in rigid but detachable connection on said battery case, said case inclosing a space beneath said cover suflicient to receive said battery leads and the junction thereof with said transmitter and receiver cords when the transmitter is so fixed thereon.

2. A telephone apparatus comprising a battery case having a cover with a depression in its upper face, a pair of spring arms projecting upward from said face, a transmitter adapted to be inset in said depression and engaged by said arms, a receiver, and flexible cord connections to establish a telephone circuit.

In witness whereof, we subscribe our signatures, in the presence of two witnesses.
